Description

TECHNICAL FIELD

The present invention relates to a field of pulse light technology, specifically to a pulse light hair removal device that is easy to use.

BACKGROUND

Hair removal, beauty, and treatment devices are comfortable, safe, and stylish home-use devices. These devices utilize advanced spectral technology to effectively prevent the regrowth of hair on various body parts, achieving permanent hair removal. The specific principle involves IPL (Intense Pulsed Light) technology, which acts on the skin. The melanin cells in the hair follicles selectively absorb this light. Under the premise of not damaging the normal skin, the heat is conducted from the hair shaft to the deep part of the follicle, quickly raising the follicle's temperature, destroying the hair papilla, thereby achieving the purpose of hair removal. Since different wavelengths have varying effects on the skin, changing the filter in the lamp head to different spectral bands can achieve skin repair and beautification functions, thus meeting precise functional needs.

In practical use, the hair removal device requires multiple functions, which are achieved by changing different lamp heads, i.e., switching different wavelengths through changing the filters in the lamp heads. However, existing hair removal/beauty/treatment devices are extremely inconvenient when changing filters. Moreover, after changing the filters, it is not clear which function corresponds to the installed filter in the lamp head, making it inconvenient to use. Additionally, during use, the situation of high voltage contacting the skin may occur, which is unsafe and causes discomfort to the body. Therefore, it is necessary to make improvements to address these defects.

In this pulse light hair removal device, an air intake channel is positioned between the air intake cavity and the head cooling cavity, and an air outlet channel is positioned between the head cooling cavity and the air suction cavity. The ends or sides of the lamp tube assembly respectively communicate with the air intake and outlet channels. The lamp tube is placed inside the reflector cup, contacting its inner wall, and both ends or sides of the reflector cup correspondingly communicate with the air intake and outlet channels.

In the described device, one side of the lower mounting plate is connected to a fan mounting board, while the other side forms an abutment with the mainboard. The fan mounting board is fixedly connected to the lower shell. The mainboard, lower mounting plate, and fan mounting board are installed together, isolating the air intake cavity from the air suction and outlet cavities.

In the device, one side of the mainboard forms an abutment with the lower mounting plate, sealing the air suction cavity. The reflector cup fixing spring is positioned between the high-voltage package and the reflector cup. An air suction port is provided on the lower mounting plate, and the cooling fan is mounted on the fan mounting board, corresponding to the air suction port.

The invention has the following beneficial effects:

The lamp head assembly in the invention is connected to the head shell on the main shell through a magnetic adsorption structure. By installing different external filters and corresponding numbers of magnets in the lamp head assembly, not only can different functional lamp heads be quickly replaced, but the Hall sensors on the PCBA board can also sense different numbers and positions of magnets in the lamp head assembly. This sensing information is fed back to the MCU (Microcontroller Unit), which automatically recognizes the replaced lamp head's function through the Hall sensors, thus facilitating easy and convenient operation.

In this invention, the conductive spring end on the PCBA board abuts against the side of the light-guiding aluminum. The conductive spring draws any accidentally induced high voltage away from the light-guiding aluminum and channels it to the ground through the TVS/ESD protection module. The design of the conductive spring and protection module ensures that there is no high voltage on the light-guiding aluminum, preventing high voltage from reaching the human skin, thus ensuring both safety and comfort.

Furthermore, an accelerometer is mounted on the PCBA in this invention. The accelerometer can automatically detect whether the device is in motion. If there is no movement, the device does not emit light, preventing unnecessary exposure and allowing for intelligent automatic light emission. This design avoids the traditional issue of multiple light emissions in one position, which can cause skin damage.

In this invention, the coordination of the air intake cavity, head cooling cavity, air suction cavity, and air outlet cavity achieves a comprehensive airway design for the entire device. This design ensures comprehensive cooling of the entire device, ensuring that all components are adequately cooled. The lamp tube assembly, located within the head cooling cavity, not only guarantees sufficient cooling effect but also is completely covered by the outer shell, preventing excess light leakage and potential eye damage. The large air suction cavity works in conjunction with this design to ensure the cooling of the mainboard and rapidly removes the heat generated by the lamp tube assembly.

The design of the elastic lamp tube holder and the reflector cup fixing spring in this invention ensures that the reflector cup remains firmly in elastic contact with the lamp tube. This ensures close contact between the lamp tube and the reflector cup under unexpected conditions and varying working temperatures, ensuring reliability and safety in operation. Additionally, the reflector cup fixing spring directs the high voltage from the high-voltage package to the lamp tube wall, ensuring reliable ignition of the lamp tube and enhancing the reliability of usage.

The multiple front mounting grooves 12 on the connecting frame 8 are symmetrically positioned on both sides, with several Hall sensors 14 set on the PCBA board 11 at positions corresponding to one side of the multiple front mounting grooves 12.

The magnetic snap-fit assembly of the lamp head assembly 4 is facilitated by the option to install varying numbers of magnets in the front mounting grooves 12. Corresponding magnets can be installed in the rear mounting grooves 13 that adhere to the magnets in the front mounting grooves 12. This magnetic connection allows for easy disassembly and assembly of the lamp head assembly 4. Different lamp head assemblies can be equipped with different external filters and corresponding numbers of magnets. The Hall sensors 14 detect the presence of different numbers of magnets in the lamp head assembly, thereby identifying the function of the currently replaced lamp head for easier operation. Furthermore, the multiple front mounting grooves 12 on the connecting frame 8 are symmetrically positioned on both sides. The connecting frame 8 has slots 29 on both upper and lower sides, but the Hall sensors 14 are only positioned on the PCBA board 11 at locations corresponding to one side of the front mounting grooves 12. This design allows for easy installation and detection by the Hall sensors, without needing to differentiate orientation during assembly or disassembly.

An air intake cavity 16 is formed between the upper shell 1 and the lower shell 2. A head cooling cavity 18 is positioned between the upper fixing plate 6, the lower mounting plate 7, and the internal filter 17 of the lamp head assembly 4. The lamp tube assembly 5 is located within the head cooling cavity 18. An air suction cavity 19 is formed between the lower mounting plate 7 and the mainboard 3, and an air outlet cavity 20 is formed between the lower mounting plate 7 and the lower shell 2.

During use, the cooling fan operates, drawing air in through the air inlet at its rear. The air passes through the air intake cavity, then through the air intake channel into the head cooling cavity. From the head cooling cavity, the air moves through the air outlet channel into the air suction cavity. The cooling fan circulates the air through the air suction port, and then it is expelled through the air supply port via the air outlet cavity and the air outlet. This full airway design creates a circulating ventilation inside the device, providing comprehensive cooling to the entire machine and ensuring all components are adequately cooled. Additionally, the lamp tube assembly being located within the head cooling cavity ensures sufficient cooling and, being fully enclosed by the outer shell, prevents any excess light from leaking out, thereby protecting the eyes from potential harm. The cooling fan, in conjunction with the large air suction cavity, ensures the cooling of the mainboard while rapidly removing the heat generated by the lamp tube assembly. The positioning of the high-voltage package is designed to ensure reliable activation while effectively dissipating heat, thereby enhancing the device's lifespan.
